The rebound device 106 may preferably be a spring (but not limited thereto, and may also adopt other keycap return design, such as magnetic retraction design, etc., the related description is common in the prior art, here is not And described between the keycap 108 and the bottom plate 104 for driving the keycap 108 back. The design of the present invention for utilizing the sliding of the support member to trigger the trigger switch can be applied to at least one of the plurality of buttons 102, the number of which depends on the actual application of the keyboard 100, and the following is directed to The button 102 shown in Fig. 2 is described. As for the structural design of the button 102 having the same design, it can be deduced.

As shown in FIG. 3 and FIG. 4 , the support device 110 is disposed between the bottom plate 104 and the key cap 108 and includes a first support member 116 and a second support member 118 . The first support member 116 is pivotally connected to the key cap 108 and Slidably connected to the bottom plate 104, the second support member 118 is pivotally connected to the bottom plate 104 and slidably coupled to the key cap 108 and pivotally connected to the first support member 116. In more detail, the first support member 116 The pivoting end portion 120 and the sliding end portion 122 are pivotally connected to the keycap 108, and the sliding end portion 122 is slidably coupled to the bottom plate 104, whereby the key cap 108 can be accompanied by the first support The pivoting movement of the piece 116 and the second support member 118 between the unpressed position and the pressed position. In this embodiment, the triggering arm 112 is disposed under the supporting device 110 and has a fixed end portion 124, an abutting portion 126, and a free end portion 128. The fixed end portion 124 is fixed to the bottom plate 104, and the abutting portion 126 is Located between the fixed end 124 and the free end 128. In addition, in order to ensure that the first support member 116 can reliably abut the triggering elastic arm 112, in this embodiment, the first supporting member 116 can further have a driving end portion 130, and the driving end portion 130 extends toward the abutting portion 126. The abutting portion 126 can be a curved arm portion and bent toward the driving end portion 130 to abut the driving end portion 130.

Here, the trigger design of the button 102 will be described. Please refer to FIG. 3, FIG. 4, FIG. 5, and FIG. 6. FIG. 5 is a perspective view of the key cap 108 of FIG. 3 pressed to the pressing position. Figure 6 is a top view of the keyboard 100 of Figure 5. When the keycap 108 is pressed by an external force from the unpressed position as shown in FIG. 3, downward (that is, to the Z-axis negative direction as shown in FIG. 3, the Z-axis and the X-axis and the Y-axis are perpendicular to each other) When moving to the pressing position as shown in FIG. 5, the first support member 110 pivots relative to the keycap 108 with the pivot end portion 120 as a pivot to slide the sliding end portion 122 outwardly relative to the bottom plate 104 (ie, The lower end of the first support member 110 slides in the positive direction of the X-axis as shown in FIG. 3, and at the same time, the driving end portion 130 can slide outward along the sliding end portion 122 as shown in FIG. The position is moved outward to the position as shown in Fig. 6, whereby the abutting portion 126 which is subjected to the abutting bias of the driving end portion 130 slides relative to the sliding end portion 130 to cause the triggering bullet The arm 112 is elastically restored from the position where the free end portion 128 is separated from the trigger switch 114 as shown in FIG. 4 (in this case, the outer shape of the triggering arm 112 is the untriggered shape as shown in FIG. 4). 6 shows the position where the free end portion 128 triggers the trigger switch 114 (at this time, the shape of the triggering arm 112 is the trigger shape shown in FIG. 6) Paul trigger switch 114 may be triggered when the elastic arm 108 is moved to the pressing position of the key top as shown in FIG. 5, the free end portion 112 of the trigger 128, such that the keyboard 100 can input data to perform the functions of the user desired.

On the other hand, when the external force is released, the rebounding device 106 can drive the keycap 108 to be returned upward by the pressing position as shown in FIG. 5 (ie, to the positive direction of the Z-axis as shown in FIG. 3) to The effect of automatic return is produced by the unpressed position shown in Fig. 3. In the above process, the first support member 110 pivots relative to the keycap 108 with the pivotal end portion 120 as a pivot to slide the sliding end portion 122 inwardly relative to the bottom plate 104 (ie, the lower end of the first support member 110) As shown in FIG. 3, the X-axis slides in the negative direction. At the same time, the driving end portion 130 can be moved inwardly from the position shown in FIG. 6 to the first position as the sliding end portion 122 slides inward. 4, the position of the bias abutment portion 126 is moved from the position where the free end portion 128 is triggered by the trigger switch 114 as shown in FIG. 6 to the free end portion 128 and the trigger switch as shown in FIG. 114 separation position.

In this way, the triggering elastic arm on the bottom plate moves along with the sliding of the first supporting member with respect to the bottom plate to cause the free end to trigger the trigger switch or to move to the mechanical trigger design that separates the free end from the trigger switch. In place of the prior art elastic trigger design that uses the elastic member to directly trigger downward, the present invention can not only greatly improve the trigger sensitivity and the pressing feel of the button, but also reduce the compressive stress on the circuit board of the button correspondingly, thereby solving the problem. The button press feeling mentioned in the prior art and the service life of the elastic member are affected, and the occurrence of damage to the circuit or continuous triggering of the switch due to improper pressing by the user is avoided. In addition, the first support member abuts the abutment portion of the trigger spring arm between the fixed end portion and the free end portion to enable the free end portion to trigger the trigger switch or separate from the trigger switch, and the present invention is The support device can be produced with only a short support member sliding stroke to complete the triggering function of the trigger switch.

In practical applications, the abutment design of the first support member and the triggering elastic arm may not be limited to the above embodiment. In other words, the relative abutment position between the first support member and the triggering elastic arm is selectively supported according to the support. The sliding stroke and the pressing of the button according to the actual application requirements of the pressure channel are optimized to adjust the trigger sensitivity and the pressing feel of the button. For example, referring to FIG. 7 and FIG. 8 , FIG. 7 is a diagram showing a driving end portion 130 that is in contact with the free end portion 132 of the spring arm 112 ′ according to another embodiment of the present invention to cause the trigger portion 134 to A schematic diagram of the trigger switch 114 is separated, and FIG. 8 is a schematic diagram of the trigger spring arm 112' of FIG. 7 elastically returning to the triggering portion 134 to trigger the trigger switch 114.

On the other hand, in the process of releasing the external force to cause the rebounding device 106 to drive the keycap 108 to automatically return, the driving end 130 can slide from the opposite side of the first supporting member 110 as shown in FIG. The position is returned to the position shown in FIG. 9, and the bias abutting end 136 is moved from the position where the free end 140 triggers the trigger switch 114 as shown in FIG. 10 to the position as shown in FIG. The position where the free end 140 is separated from the trigger switch 114. The invention is characterized in that the first support member abuts against the abutting end portion to pivot the free end portion relative to the pivoting portion to trigger the trigger switch or separate from the trigger switch, and the present invention can be based on the support member sliding stroke and the button press The practical application requirements of the pressure channel appropriately adjust the ratio of the abutting end and the free end of the free end to the pivoting portion (for example, 1:1, etc.) to optimize the trigger sensitivity and the pressing feel of the button.

It is worth mentioning that the present invention can also use the second support member to drive the triggering arm to trigger the trigger switch. Please refer to FIG. 11 and FIG. 12, and FIG. 11 is a diagram of another embodiment according to the present invention. A perspective view of the proposed keyboard 200, and FIG. 12 is a perspective view of the button 202 of FIG. 11 being pressed. The embodiment has the same number as the components described in the above embodiments, and represents the same structure or function. The related description will not be repeated here. As shown in FIG. 11 and FIG. 12, the keyboard 200 includes a plurality of buttons 202 (in order to clearly display the button structure design of the keyboard 200, only a single button 202 is shown in FIGS. 11 and 12), the bottom plate 104, and a rebound device 106. The button 202 includes a key cap 108 (shown in phantom in FIGS. 11 and 12) and a support device 204, and is disposed on the bottom plate 104 for the user to press to perform the function desired by the user. There is a triggering arm 206 and a triggering switch 208 opposite to the triggering arm 206. The supporting device 204 is disposed between the bottom plate 104 and the keycap 108 and includes a first supporting member 116 and a second supporting member 210. The first supporting member 116 The first support member 210 is pivotally connected to the bottom plate 104 and is slidably coupled to the key cover 108 and pivotally connected to the first support member 116. In this embodiment, the triggering arm 206 is disposed on the outer side of the second support member 210 and has a fixed end portion 212, an abutting portion 214, and a free end portion 216. The fixed end portion 212 is fixed to the bottom plate 104. The connecting portion 214 is located between the fixed end portion 212 and the free end portion 216. The second supporting member 210 has a pivoting end portion 218 and a sliding end portion 220. The pivoting end portion 218 is pivotally connected to the bottom plate 104, and the sliding end portion 220 is slidable. Connected to the keycap 108, whereby the keycap 108 is It is possible to move up and down with the pivoting of the first support member 116 and the second support member 210 between the unpressed position as shown in FIG. 11 and the pressed position as shown in FIG.

Here, the trigger design of the button 202 will be described. As can be seen from FIGS. 11 and 12, when the key cap 108 is pressed by an external force from the unpressed position as shown in FIG. 11 (ie, as shown in FIG. 11 When the Z-axis negative direction shown is moved to the pressing position as shown in FIG. 12, the second support member 210 pivots relative to the bottom plate 104 with the pivot end portion 218 as a pivot so that the sliding end portion 220 is pivoted. The keycap 108 slides outward (ie, the upper end of the second support member 210 slides in the positive X-axis direction as shown in FIG. 11) to bias the abutting portion 214 (for example, by using a bump formed on the sliding end portion 220). The 221 bias abutment 214, but not limited thereto, moves to the free end 216 to trigger the trigger switch 208 as shown in Fig. 12 (at this time, the trigger arm 206 is shaped as shown in Fig. 12). The position of the trigger shape is such that the keyboard 200 can perform the function that the user desires to input. On the other hand, the external force is released to cause the rebounding device 106 to drive the keycap 108 to automatically return from the pressing position as shown in FIG. 12 (ie, to the positive Z-axis direction as shown in FIG. 12) to the first position. During the unpressed position shown in FIG. 11, the second support member 210 pivots relative to the bottom plate 104 with the pivot end portion 218 as a pivot to slide the sliding end portion 220 inwardly relative to the keycap 108 (ie, The upper end of the two supporting members 210 slides in the negative direction of the X-axis as shown in FIG. 11 , whereby the abutting portion 214 can slide relative to the inward direction of the sliding end portion 220 to elastically return the triggering arm 206 to The position where the free end portion 216 is separated from the trigger switch 208 (in this case, the outer shape of the trigger arm 206 is the untriggered shape as shown in Fig. 11) is shown in Fig. 11.

In this way, the triggering elastic arm on the bottom plate moves along with the sliding of the second supporting member with respect to the key cap to cause the free end to trigger the trigger switch or move to the mechanical trigger design that separates the free end from the trigger switch. In order to replace the elastic trigger design that directly triggers the downward triggering of the elastic member in the prior art, the present invention can not only greatly improve the trigger sensitivity and the pressing feel of the button, but also reduce the compressive stress on the circuit board of the button correspondingly, thereby The problem of the button pressing feel mentioned in the prior art and the service life of the elastic member being affected is solved, and the occurrence of damage to the circuit or continuous triggering of the switch due to improper pressing by the user is avoided. It should be noted that the abutting design of the second supporting member and the triggering elastic arm is not limited to the 11th and 12th drawings. For example, the first supporting member mentioned in the above embodiment is in contact with the triggering elastic arm.
